Method for solving section temperature difference of broad kiln

Abstract

The present invention discloses a method solving wide kiln cross-section temperature difference, the wide kiln includes the ejection gun burning mouth channel passing through kiln bulk and the ceramic roller installed in kiln bulk calcined zone and used for laying products; the steps of the method solving wide kiln cross-section temperature difference as follows: a. said kiln bulk calcined zone is equipped with the fuse channel additionally which is penetrated with the ejection gun burning mouth channel; b. two sides temperature of the wide kiln is reduces; c. combustion air amount is reduced; the circumference of said fuse channel about is 1 / 4 of inner diameter of kiln bulk calcined zone; the circumference of said fuse channel about is 1 / 3of inner diameter of kiln bulk calcined zone. Theinvention increases the length of the calcined channel, can guide flame into the middle zone of kiln bulk calcined zone, so reduces the cross-section temperature difference of kiln bulk; it decreasesthe calcined time of products, the size differences in left, central and right direction of calcined products are controlled in 2-3 mm, the color-difference is reduced, the products passing percent is significantly increased, product quality is stable, the product cost is reduced and it has vast market economic benefits.

Description

technical field [0001] The invention relates to a method for solving defects in a kiln used for firing building decoration materials, in particular to a method for solving the temperature difference in the cross-section of a wide-body kiln. Background technique [0002] "Science and technology is the primary productive force", a belief shared by people all over the world today, is the power source for countless countries to improve their national economies. In the first year of China's "Eleventh Five-Year Plan", "independent innovation" is the central point for every enterprise to enhance its competitiveness and exert its subjective initiative. In the prior art, ceramic tiles have become the object of customers' choice due to their high density, small shrinkage and deformation, good wear resistance and good decorative effect, and have a broad market.

Problems solved by technology

In the prior art, ceramic tiles have become the object of customers' choice due to their high density, small shrinkage and deformation, good wear resistance and good decorative effect, and have a broad market. There are cross-sectional temperature differences in the production process of the body roller kiln, especially when the production is increased and the firing cycle is shortened, the size difference between the left, middle and right sides of the product will be too large, and the product will have a lot of color difference, which seriously leads to a decline in the product qualification rate. Ceramic enterprises have caused relatively large economic losses. The front end of the burner channel of the spray gun with a high-temperature zone in the prior art wide-body kiln is terminated at the inner wall of the kiln body. Certain restrictions, the flame injection area is small and scattered, and it can only be injected at about 1 / 3 of the porcelain roller used to place the product, so that the temperature in the firing area is uneven, and the temperature on both sides of the kiln body is high, resulting in a cross-sectional temperature difference. All parts of the product are heated unevenly, resulting in low yield, large color difference, low pass rate, long firing cycle and high product cost.
